It is well known that petroleum distillates methanol containin products of a higher or products of cracking processes which are order than methanol: marketed as gasoline and the like, are very In testimony whereof I have hereunto set much inclined to knocking when used as my hand. I

' WILHELM GAUS. I have now found that-this great drawback can be diminished or even completely removed by an addition of methanol to gasoline. Comparatively small quantities of methanol, generally not over 12' per cent by volume, are suflicient for this purpose so that the calorific power of the fuel is not diminished-to any substantial degree.

Preferably the methanol is employed in the anhydrous state, as methanolcontaining water is only slightly soluble in gasoline. In order to further increase the solubility of methanol, mixing facilitators such as for example higher aliphatic alcohols, ketones and the like, may be added. Crude synthetic methanol containing isobutyl alcohol and the like, may be employed as it is obtained in its manufacture in the process according to the present invention.

For example, valuable fuel mixtures are obtained by mixing 96 parts, by volume, of American gasoline of 0.75 specific gravity with 4 parts of anhydrous methanol or by mixing 88 parts of gasoline with 12 parts of crude synthetic methanol about two thirds of which consists of methanol and about one third of which consists of products of a higher order than methanol. The composition of crude. synthetic methanol after. removal of water is for example about as follows :72 per cent of methanol, 13 r cent of isobut 1 alcohol, 15- per cent 0F higher alcohols, l ietones and the like.

The above examplesare only given for the pur of illustration. and the invention is V not imited thereto.

What I claim is:

1.-A com ositionof matter substantially composed o gasoline, and not more than 12 per cent by volume of the gasoline of crude synthetic methanol containing products of a higher order than methanol.

2. A composition of matter comprising asoline and between about 4 and 12 per cent y volume of the gasoline of crude synthetic
